Torn Jeans during presentayion

I am very disappointed in Levi's this is the brand of my choice for life. Finally convinced my lady because they are the best with Jeans for curved woman. Today she had a presentation and mid-present the jeans wripped from the side. she was angry at me as it was the first time she worn it. I no longer have the slip and i feel let down as she won't believe in the brand as I do. I do not know what she will do with the other 2 i bought her because i believed in the brand this much.
